Be it known that we, JAMES'POWERS and JOHN G. ScHoPmLn, citizens of the United States, residing, respectively, at Newark, in the county of Essex and State of New Jersey, and at \Vashington, District of C olumbia, have invented a new and useful Tool for Applying Glaziers Points, of which the following is a specification.

The invention relates to improvements in tools for applying glaziers points.

The object of the present invention is to improve the construction of tools for applying glaziers points, and to provide a simple and comparatively inexpensive hand tool, designed principally for use in putting in glass in the sashes without IQIIIOXlIlgihB latter from a window, and adapted to be conveniently'used ,in any position, and capable of rapidly and accurately driving glaziers points without danger of breaking the glass.

. With these and other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in'the claims stood that various changes in the form, proportion. size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of-the advantages of the invention.

-ner faces of its sides with inwardly exhereto appended; it being, under-' Fig. 9 is In the accompanying drawings in which is illustrated the preferred embodiment of the invention, 1 designates a hollow bar, constituting one member of the device and constructed of stout sheet metal, or other suitable \material and composed of spaced parallel sides, and'a connecting back portion. .The hollow bar 1, which forms a casing for a magazine 2, is provided'at the intendinglongitudinal flanges 3, constituting a guide for the magazine 2 and adapted to maintain the ,samein proper position and preferably formed by a metallic shell 4, constructed of relatively thin sheet metal ED STATES PATEN E j and composed of spaced sides and a connecting back or bottom portion to conform to the configuration of the hollow bar 1, andhaving the longitudinal edges of its sides bent inward atright angles to form the said .fianges 3. The interio-rly arranged sheet metal shell is secured by rivets, or other suit-able fastening means to the h0llow bar. The interiorly arranged flanges may be formed by angle strips or any other suitable means.

The magazine 2, whichis constructed-of sheet metal, or other suitable material, consists of a front V-shaped portion 5 and a rear tubular portion 6, and it is provided at .its rear end with a rectangular head 7 to fit the interior of the hollow bar. The

V-shaped portion 5, which extends to the' .front or outer end of the hollow bar, is 9 adapted to receive the glaziers points and is supported at its outer end by a'block or piece 8, soldered or otherwise secured within theouter end of the bar 1 and having a V-shaped recess or opening 8? to fit the V-shaped portion of the magazine. The V-sh'aped front portion 5 is of sufficient size to receive the various sizes of glaziersl points 9, which are arranged ina stackwithin the V-shaped portion 5, as clearlyillustrated in Figs. 2 and 3 of the drawings, and the points 9 are automatically fed forwardly or outwardly b nie'ans of a coiled spring 10, arranged within the inner. or rear ortion of the magazine and equipped at its front or outer end with a follower or head -11 and engaged at its inner or rear end by an adjustable tension controlling decured to the spring 10 in any preferred illogmanner. The magazine is locked in the hollow bar 1 by means of a spring catch 13.,

consisting of a piece of spring metal, ar-

' arranged exteriorly of the back or connectfastening-device and having its outer terminal pbrtlon angularly bent to form an engaging shoulder-1'5 and extended to provide a projecting finger piece 16 by'means of which the catch is pressed outwardly to release the magazine when it is desired to remove the same from the hollow bar 1.

The tension controlling device consists of a rectangular sleeve 17 to slidably embrace the hollow bar, and a rod 18 extending into the inner or rear portion of the coiled spring and supporting the same. The sleeve 17 is provided at the bottom or outer portion with a slot 19 of a width-to receive the spring'catch to permit the said sleeve to be placed on and removed fron'rthe bar 1.

Therod 18 is provided at its rear end with an angular bend forming an arm 20, secured to the top or inner transverse ortion of the sleev and forming a stop or the inner or rear end of the coiled spring and operating in a longitudinal. slot (3 in the inner tubular portion 6 of the magazine. The slidable sleeve 17 is equipped with a pawl 21, pivoted at one end by a rivet 22, or other suitable fastening device to' the outer face of one side of the sleeve and provided at its free end with a laterally extending flange or tooth 23, adapted to engage notches 24 formed in the longitudinal edge of one of the sides of the hollow. bar -1. The pawl is provided at an intermediate point with an outwardly extending lip or flange 25, adapted to be engaged by the finger to enable-the pawl to be readily swung into and out of the notches of the hollow bar 1. The slidable sleeve is adapted to be advanced as the glaziers points are consumed, so as to maintain; the springat the propertension for positively feeding the points 9. The magazine may be removed.

for filling the same, or the points may be supplied to the magazine through notches 26 and. 27, formed in the longitudinal flanges 3 of the hollow bar. The V-sh-aped portion 5 of the magazine is provided at op posite sides 'With notches 5, which register with the notches 27 of the longitudinal flanges 3.

The sides of the hollow bar are enlarged at the outerends thereof at 28, and they are preferably provided at their outer faces with blocks or pieces 29, adapted to space the sides or ends 30 of a combined guard and stop 31 from transverse guide flanges '32 of the enlarged portions 28 of the sides of the'liollow bar 1. The enlarged outer portions 28 have their. front transverse edges bent laterally to form the guide also provided with inwardly extending guide flanges 32, which fit against the inner or rear face of the relatively heavy portion 35 of the driving plunger. The combined guard and stop 31 is approximately U-shaped, and its side or end portions 30 are The enlarged portion of the bar 1 is secured by screws 37, or other suitable fastening devices to the outer faces of the spacing blocks or pieces 29, but they may be mounted on the bar -1 in any other desired manner. The transverse portion of the combined guard and stop is located opposite the triangular, opening or recess 8 of the end piece 8, and it forms a stop for the outermost glazier point 9, and it also serves as a guard to prevent the driving plunger from coming in contact with the glass.

The solid relatively heavy ortion of the .driving plunger is provide with a socket 38, which receives a rounded head 39 of a plunger actuating bell crank lever 40, composed of longitudinal and transversely disposed arms and. pivoted at the junction of the arms by a rivet 41, or other suitable fastening device, which passes through a pair of spaced ears 42, formed integral with the sides of the hollow bar and bent inwardly with a rounded outer edge 43, and it has a shoulder 44 located at the inner end of the longitudinal arm at the outer side edge thereof and at one end of the rounded edge 43. The shoulder 44 is arranged to be en-- gaged by a dog 45, pivoted at its front end by a rivet 46, or other suitable fastening device between spaced projecting portions 47 of an operating lever 48, and provided at the inner or rear end with an approximately L- shaped arm 49, extending longitudinally of the operating lever.and provided with a set screw 50. I The inner end of the dog 45 engages with the shoulder 44 of the bell crank lever, and the setscrew is adjustable to regulate this engagement and to control the tripping of the operating lever. The operating lever, which is constructed of stout sheet metal or; other suitable material, is provided at its outer end with transversely disposed inwardly extending arms 51, spaced apart and pivoted by a transverse pin 52, or other suitable fastening device to the ears 42 of the bar 1. The operating lever and the bar 1 :are'ada ted to be grasped with one hand and '40 is provided at the junction of the arms crank lever is oscillated against the action of a relatively heavy coiled spring'53." As the bell crank and the operating levers have different I centers-of oscillation, the swinging movement of the operating lever actuates the bell crank lever until the dog is carried automatically beyond and out of engagement with the shoulder 44. The bell crank lever is then tripped and released, and is oscillated by the heavy coiled spring 53, which is compressed by the action of the operating lever. The initial movement of the bell crank lever slides the driving plunger outward, and the heavy coiled spring 53 moves the same inwardly with sufiicient force to drivefthe gl'aziers" points into the wood of -the sash to the desired depth. The heavy I coiled spring is interposed between the transverse arm of the bell crank lever and an approximately L-shaped plate or piece 54, secured between theenlarged portions 28 of the sides of the hollow bar, as clearly shown in Fig. 2 'of'the drawings. The transverse arm of the bell crank lever and the plate 54 are preferably provided with bosses 55 and 56 to extend into and engage the end coils of the springs 53 to prevent displacement of the latter. The dog 45 is moved-inwardly by a fiat spring57, secured at one end by a screw 58, or other suitable fastening device to the inner face of the operating lever and having its other endenga'ged in a notch 59 the operating lever is-moved outwardly, the

. spring 57 reengages the dog 45'with the shoulder 44.

The operating lever is limited in its inward movement and is automatically opened and moved outwardly by means of a spring device, consisting of a tubular member 60, a

coiled spring 61 and a rod 62.- The tubular member, which receives the inner portion-of the coiled spring 61, is provided at its inner end with a transverse head or flange 63 cut away at the center at 64 to clear the' nagazine, and provided at opposite sides with re .cesses 65, which engage with notches 66 in the side edges of the bar 1, whereby the tubular member is seated thereon and is interlocked therewith. The outer end 67 of the pin 62 pierces the operating lever and is headed, as clearly shown in Fig. 2 of the drawin s." The" pin 62 extends into and suppats t-e adjacent end of the spring 61. en the operating lever is actuatedby the operator, the sprin 61 is compressed and its inward movement 1s limited bythe tubular member," which prevents the operating. lever pinching the hand of the operator. As

As soon as dog with the bell crank lever. When at drlvin' plunger moves outwardly a sufiiclent istance to uncover the said recess or opening 8 of the end piece 8, the spring ac- I tuated follower of the magazine automatically feeds the glaziers points outwardly and the outermost point is carried beneath or in front of the thin driving portion of the plunger, and is in position to be actuated by the same when the bell crank lever is tripped through the continued inward movement of the operating lever. The spring through the adjustable tension controlling device is adapted to maintain and hold the points firmly in position for driving, when the tool is in any position, whereby the tool is adapted for applying glaziers points to a sash githout removing the same from the win- Having thus fully described our invention, what we claim as new and 'desire to secure by Letters Patent, is
